Abstract:The aging treatment process of Ti65 high-temperature tianium alloy was studied. The tersile property at room temperature and ternsile property, endurance property, creep property and thermal stability at 650 °C of the alloy were tested. The results show that Ti65 high-temperature titanium alloy has good thermal stability by aging treatment at 700 °C. By increasing the aging time, the creep porperty of the alloy is improved. By increasing the aging time and aging temperature, the properties of Ti65 alloy are reduced.
Key words: Ti65 alloy; aging temperature; aging time; mechanical property; thermal stability
